Application filed July 2, 1913. Serial retrace r.

tively in a convenient manner from a common operating member.

The'invention comprises the parts, 1m-- provements and combinationshereinafter described with reference to the accompanying drawings andmore particularly pointed out in the claims.

In the said drawings: Figure 1 is a front elevation of a valve structureembodying the invention; Fig. 2 is a front elevation of anotherembodiment; Fig. 3 is a sectional plan view illustrating the applicationof the principles of the invention to a four-valve structure; Fig. 4 isa side view of Fig. 3; Fig. 5

is a plan view of Fig. 1, the operating shaft, being shown in section;Fig. 6 1s a vertical sectional view illustrating the construction ofFig. 2 with the supplementary plate shown in Fig. 8; Fig. 7 is a planview of the shutter-like valveactuating member, dottedlines being usedto indicate its various positions with respect to the plunger valves;Fig. 8 is a detail view of apart shown in Fig. 6; Fig. 9 is a plan viewofthe follower plate shown in Figs. 1 and 5; and Fig. 10 is an elevationthereof.

The device includes a valve body, such as indicated at 10 in Fig. 1 or10 in Figs. 2

and 6, the same being provided with a plurality of valve chambers 11, inthis instance two in number. Parallel bodily-movable valves, in thenature of plunger valves 12, operatewithin the body and have valve heads13 which cooperate with suitable seats 14:. The fluid may enter at thebottoms of the chambers and'escape through the lateral passages 15 whenthe valves are open, or vice versa. At their upper or outer ends thestems of the valves are provided with suitable buttons 16, constitutingvalve pro jections to be engaged by the actuating mechanism.

These buttons operate in env larged bores .17 formed in theg loodyand.are acted upon by expansion springs 18, which are confined withintheserfbores and tend to close the valves.

A common rotary operating member, in the form of a shaft 19 having ahandle 20, 1s mounted-in the valve body in axial parallelism with thevalves, and is provided with means whereby. its rotation produceslongitudinal movement of a selective actuating member 21.

In the construction shown in Figs. 1, 5, 9 and 10, the rotary movementof the handle is converted into endwise movement of the actuating memberthrough the engagement of a cross-pin 22 in the shaft with a double cam23fon a follower plate 24, the cam-engaging. parts being made double tobalance the thrust; An obvious reversal would be to mount the cam on theshaft and cooperating contact points or surfaces on the, follower. Inthe particular construction shown, stops 25 are formed at the ends'ofthe cam inclines, so as to limit the shaft to a partial revolution. 'Atone extreme of the limit of handle movement the projecting.

portions of the pin 22 rest on the low portions of the cam, so that thefollower is in its highestposition with the valves closed, while at theother extreme of movement the pin bears against the high portions of thecam, with the result that the follower is in its lowermost position withthe valves unseated. -In thisconstruction the shaft is rotatable in abearing in the valve body in "t-ermediate the valves, and is heldagainst endwise movement in an upward direction by ahead 26 on its lowerend'within a recess in the body. The selectivevalve-actuating member 21.is disposed intermediate the follower 24 and the valve projections 16,so that downward movement of the follower, produced by the rotation ofthe operating shaft, forces the actuating member against one mother ofthe valves to unseat the same. v

As shown more particularly in Fig. 7, the preferred form of selectiveactuating means comprises a shutter-like plate provided with anaperture, whereby it is mounted to swingon the operating shaft beneaththe follower, and with two wings 28 which are so formed and proportionedas to enable the actuating member to overlie either or both of thevalves, as indicated inthis view. Inter-c.

mediate the wings it is provided with a suitable handle 29, whereby itmay be conveniently shifted. While this shutter-like plate constitutesthe preferred form of selective valve-actuating means, it will beunderstood that the advantages of the invention may be realized withvarious other forms of transversely-shiftable devices.

The follower plate 24 is preferably eX- tended over thevalveprojections, opposite which it is provided with openings 30 ofsufficient size to allow these projections to pass through without beingactuated when the follower is depressed, provided that one or both ofthese openings is not closed by the shutter-like actuatingmember. Meansare provided for holding the follower against turning, a suitableembodiment of which is illustrated in the form of a pin 31 dependingfrom the follower in position to contact with a side face of the valvebody. hen the handle is turned to close the valves, the follower 24 andactuating member 21 are restored by an expansion spring 32, which isinterposed between the actuating member and valve body. The actuatingmember 21 is thus held between this spring and the follower, and in thismanner is kept from turning with the shaft when the latter is rotated.It will be observed that the inclines.

of the cam member 23 are of such gradual character as to render thevalve mechanism self-holding at any degree of opening.

The construction shown in Figs. 2 and 6 is substantially similar to thatjust described, but differs therefrom in the manner of mounting theoperating shaft 19 in the body 10 and the means whereby turning of thehandle produces. longitudinal movement of the actuating member. Inaccordance with this construction, the lower or inner portion of theshaft is screw -thread ed, as shown at 33, and engages with a threadedopening in the body instead of being merely rotatable in a bearing as inthe other form. Thus, the operating shaft has endwise as Well as rotarymovement, and the endwise movement is imparted to the follower 24 andthe actuating member 21 through a collar 34 on the shaft overlying thefollower. The follower and the shutterlike actuating member both engagean unthreaded portion of the shaft and are held in position by thespring 32, which restores these parts when the handle is turned in thevalve-seating direction. It will be understood that the follower 24 isheld against turning in the same manner as in the other construction.

Figs. 6 and 8 illustrate a further feature of the invention whichcomprises a supplementary plate or transversely-shiftable member 10,which is also rotatably mounted about the operating shaft and movableindependently of the member 21, so that it may cooperate with eitherwing thereof. This provides means whereby when the member 21 is set toopen both valves, one valve may be opened to a greater degree than theother. By shifting the supplementary member to midposition it affectsneither of the valves. The forms of the invention which have beendescribed are two-valve structures, but it will be understood that theprinciplesof the invention are not limited to any specific number ofvalves. Figs. 3 and 4 illustrate a four-valve construction, and inaddition show certain further features of the invention which may beem-- ployed with advantage in certain instances. The valve body 1Qcomprises four valve chambers, in which are four plunger valves, theprojecting plungers of which are desig nated 16 as in the precedingviews. The valves are preferably arranged symmetrically, 90 apart, abouta common operating shaft 19*. This shaft may be the same as the shaft 19of Fig. 1 or the shaft 19 of Fig. 2, or of other suitable character, butas illustrated it resembles the construction of Figs. 2 and 6. Thetransversely-shiftable, selective valve-actuating means is here shown asa single, elongated member 21 pivoted at one end on the operating shaftand extended at the other end to form an operating handle 29, and beingof such width as to be capable of being positioned in inoperative,intermediate relation to the valves. \Vhen in this position theoperating shaft may be screwed down until the valve projections arereceived. within recesses 30 in the follower 2e", these recesses beingclosed at the top by caps or hollow bosses 4-1 so as to protect thevalves from tampering. Means are provided for locking the parts in thisrelation. Such means may be widely varied, but for purposes ofillustration 1 have shown a padlock 12 the shackle of which passesthrough an opening in a pin 13, which in turn is passed throughregistering openings in lugs 44:, 15 on the follower and valve bodyrespectively. The shank may also passthrough an opening in the actuatingmember 21 though obviously this is not essential. In this construction,when the mechanism is unlocked and the follower and actuating memberraised, the latter may be swung into operative position over any one ofthe valve members, so as to unseat the same upon depression of thefollower.

Fig. 4 shows the follower 2% locked down directly against the top of thevalve body, the member 21 under this condition being received within arecess .46 in the valve body means for moving said valve-actuatingmember toward and from the valves, said valve-actuating member beingalso mounted for guided movement relatively to said operating member andthe valves so as to actuate said valves selectively.

2. The combination of a valve body, a plurality of parallel plungervalves therein, a valve-actuating member movable toward and from thevalves in a direction parallel to their axes, and a rotary member foroperating said valve-actuating member, the said valve-actuating memberbeing mounted so as to be shifted transversely of the axes of saidvalves independently of said rotary operating member and being of suchextent as to be capable of displacing one or more of the plunger valvesat will.

3. A valve structure comprising a valve body having a plurality of valvechambers and seats, plunger valves cooperating therewith, and a rotaryoperating shaft mounted in said body and provided with a handle, incombination with a valve-actuating member adapted to be movedlongitudinally by said shaft and being pivoted so as to be capable ofswinging into positions where it operates one or other of the valves atwill.

In a valve structure, the combination of a plurality of parallelbodily-movable valves, a valve-actuating member, and a rotary operatingmember axially parallel with said valves-and having means for moving theactuating member longitudinally to unseat the same, said actuatingmember being angularly shiftable about the axis of the operating memberfor selective actuation of the valve.

5. In a valve structure, the combination of a plurality of plungervalves, an operating shaft, a follower actuated by the shaft, aselective valve-actuating member interposed between said follower andthe valves and having an opening receiving the shaft about which it maybe rotatably shifted, and a spring for restoring said follower andactuating member, said actuating member being interposed between thespring and follower.

6. Ina valve structure, the combination of a plurality of plungervalves, a rotary operating shaft, a follower thereon moved axiallythereby, and a selective valve-actuating member disposed shiftablybetween said follower and the valves so as to actuate the latterselectively.

In a valve structure, the combination of a plurality of plungervalves, a rotary operating shaft, a follower adapted to be movedlongitudinally thereby and having openings through which the projectionsof the plunger valves may pass, and a shutterlike valve actuator mountedto swing about the axis of the shaft for selectively closing saidopenings.

9. In a valve structure, the combination of a plurality ofbodily-movable valves, a rotary operating member, and two or moresuperposed plates between said operating member and valves, said platesbeing independently shiftable transversely of the direction of valvemovement so as to effect variable and selective operation of the valves.

10. In a valve structure, the combination of a plurality ofbodily-movable valves, a rotary operating member, a valve-selectingmember movable longitudinally by said op; erating member to actuate thevalves and transversely shiftable independently of the operating memberfor valve selection, and
